Hybrid Cameras - The Best Of Both Worlds

By Paul Stevens


Hybrid cameras, also known as mirror less cameras, are a new strain of camera that combine the compactness of your compact digital camera together with the image quality of a digital single lens reflex camera. The modern hybrid cameras don't have a single lens reflex mirror removing some of the bulk of a DSLR, but have a larger image sensor than your standard compact digital for better photos. A hybrid camera also does not have a normal viewfinder as in a DSLR, but rather uses an LCD screen or an electronic viewfinder that can be purchased separately. The hybrid cameras have interchangeable lenses similar to a DSLR, making them versatile enough to get many types of shots. They also take incredible HD video in 780p or 1080p format.

Hybrid cameras are the answer to that middle market of consumers who do not want to invest in high end DSLRs, but want to get excellent quality pictures than a compact digital. The hybrids are compact enough to carry around without difficulty. On many models, you are able to instantly record HD video without dealing with a menu. Most models run in the $300 - $1,000 range, which makes them very affordable to many people.

Olympus and Panasonic use what is called a micro four thirds format for interchangeable lenses. It is an attempt to make a standard format for digital camera lenses making it possible to change with advanced DSLR lenses. Micro four thirds refer to the ratio of the image sensor, which is a 4 X 3. This size is smaller than an average 35mm, but about 10 times larger than a standard digital compact. The increased size and quality allow the photographer to shoot in lower light without the graininess connected with smaller image sensors.

Many major camera brands have come out with their own version of a hybrid camera. Panasonic led the way with the Lumix G1, then came Olympus with the PEN series. Sony announced the NEX 3 and 5. Nikon and Canon have plans to create hybrids very soon.

With all of the hype surrounding the modern hybrid cameras, it remains to be seen if the market for this type of camera will take off. Sales have steadily increased since 2008 and it's predicted to take off by 2012.

Hybrids provide you with the best of both worlds. They're compact enough to carry around easily and powerful enough to take great photos.

But that's great because it only means good things for you, the consumer. This competition drives the technology forward developing new features and innovations. Find the best pocket size camera for your needs by learning about some of the new features to be on the lookout for.

The consumer reaps the benefits as companies try to outdo each other, because, while there are hundreds of choices available, there is no apparent decline in demand for feature rich digital cameras. The following digital cameras are good ones to consider if you're in the market for something special.

To begin, we'll do a short review of the Fujifilm FinePix F80EXR which by all accounts is a very respectable compact pocket size camera. Some may find this camera's mega-zoom feature appealing. The 12 megapixels of this camera mean you can create clear, large prints. It is reasonably priced for the advance features it offers. The EXR sensor offers three different modes to choose from. This essentially gives you three types in one camera. There are three modes: highest possible resolution mode; optimum dynamic range mode; and the lowest possible noise mode. Also, going further, the F80EXR will automatically analyze the scene and make the best choice for you - a bit impressive, we think.

For someone who just wants a point and shoot camera without overly powerful zoom, the Panasonic Lumix DMC-FH20 is a great option. This ultra compact camera includes a built in flash and LCD and has 14.1 megapixel resolution. The LCD uses an active matrix TFT technology design. Because this camera has no optical viewfinder, you use the 2.7 LCD display to review and frame your shots. There is an optical image stabilization system for shake compensation.

We've included Canon's PowerShot SD750 in this article because it is a good overall pocket size camera. You'll find a solid digital camera that includes greater than average movie quality plus face detection, of course. We find the photographs the camera produced to be high ISO quality. There is no better choice for a digital camera when it comes to an ultra-compact design and large LCD screen. People who prefer not to look through the viewfinder to snap photos but wish to use the LCD display instead are the perfect market for this camera. This particular LCD screen is 3 inches and may not be as clean or crisp as other screens but is easy to see in the sun. As far as digital pocket size cameras are concerned, Canon has one of the best reputations in the marketplace. While these are old workhorses, they've continued to be loved by many of the more casual photographers who love taking snapshots on the go. It's possible to find cameras that offer more features - for a larger price.
